Bush cutter comprising catalase hush tube, swirl sprayer and two-stroke multi-scavenging-port gasoline engine

Abstract

The invention relates to a bush cutter for cutting off shrubs and shaping flowers and trees in fields such as flower beds, yards, parks and road sides. According to the bush cutter comprising the improved multi-scavenging-port small-size two-stroke single-cylinder air-cooled gasoline engine, the original long rod is changed into the multi-honey-comb and catalase hush tube, the bush cutter comprises a transparent protective cover, a bush knife with an external peripheral knife edge and an internal peripheral knife edge, a long rod interface with a side flange and a side screw thread and being hard to loose, a vibration decreasing handle with a spiral spring or a wave-shaped spring, and a carburetor with an internal spiral vortex sprayer, the bush cutter is a novel bush cutter comprising the catalase hush tube, the swirl sprayer and the two-stroke multi-scavenging-port gasoline engine, and the bush cutter has the benefit effects that the discharge is low, a discharge port is far away from people, the safety performance can be realized, and the quality and the practicability are improved; and a new operation mode of the bush cutter can be further provided, so that the work semidiameter can be enlarged.

Description

technical field [0001] The present invention relates to a shrub cutter for cutting shrubs in flower beds, gardens, parks and roads, especially a small two-stroke single-cylinder air-cooled gasoline engine with improved multi-scavenging ports, such as E134F, The original long rod is changed to a muffler tube with multiple honeycombs and catalysts, a transparent protective cover, a brush cutter with an outer peripheral blade and an inner peripheral blade, and a long rod interface that is not easy to loosen with an edge flange and a side threaded buckle. The handle with helical spring or wave spring and vibration damping, the carburetor with inner spiral vortex nozzle, is a new type of brush cutter with catalyst muffler pipe, vortex nozzle and two-stroke multi-scavenging port engine. Perhaps it can be said that this innovative method is not directly discharged by an engine close to people, but indirectly discharged through a 1.5-meter-five catalyst muffler pipe. A new technical ...
